Description of the Invention: [Technical Field of the Invention] [0001] The present invention relates to a heater, and more particularly to a fin ceramic heater. [Prior Art] [0002] Positive temperature coefficient (PTC) ceramics, self-heating after energization causes the resistance value to enter the transition region, and the resistance value increases rapidly with increasing temperature within a certain temperature range. Widely used in thermostat heaters, household appliances, vehicle heating and line protection, etc. PTC ceramics are made by adding a small amount of rare earth elements to materials such as barium carbonate and bismuth telluride, which are sintered at high temperature and will remain stable over a wide temperature range. The low resistance value, when the temperature is higher than the Curie temperature of the material, its resistance value will increase greatly. [0003] A conventional heater has a positive temperature coefficient ceramic resistor sheet, and a conductive metal sheet is attached to both sides of the positive temperature coefficient ceramic resistor sheet. The conductive metal sheet has a conductive terminal and is electrically connected to the external power source by the conductive terminal. The power is obtained, and the current passes through the two conductive metal piece and the positive temperature coefficient ceramic resistor piece, so that the positive temperature coefficient ceramic resistor piece generates heat, and the heat generation amount is the square of the current X resistance, but the heat conduction surface and the external contact area are not large, so that the heat is insufficient. Therefore, a fin is disposed on one side of the conductive metal piece for conducting heat generated by the positive temperature coefficient ceramic resistor, and is electrically insulated from the outside to improve safety, and needs to be tight between the fin and the conductive metal piece. An insulating plate is sandwiched to block the current of the conductive metal piece to guide the fin. However, due to the flatness factor of the fin, the conductive metal piece or the insulating plate, the pressure stress applied to the insulating plate is unevenly distributed, and the insulation is insulated. Plate change 099102069 Form number A0101 Page 4 / Total 23 page 0992004007-0 201127181 [0004] Type and cracks, and thus reduce the insulation board Insulation capability. In view of the above prior art, the present inventors have made great efforts to improve and enhance the performance by using the research and the use of the theory, and finally can propose a design that is reasonable and effective. SUMMARY OF THE INVENTION An object of the present invention is to provide a fin ceramic heater capable of enhancing the insulation of a heater. [0006] In order to achieve the above object, the fin ceramic heater comprises a ceramic heating structure, a pair of electrode plates, a plurality of insulating sheets, an insulating adhesive, and a pair of fins; the pair of electrode plates are respectively attached The ceramic heating structure has two sides; the insulating sheets are respectively attached to the outer side surface of the pair of electrode plates in a series manner, and a gap is formed between any two adjacent insulating sheets, and the width of the insulating sheet is larger than the The width of the electrode plate; the insulating adhesive is filled in the gap; the pair of fins are respectively stacked on the insulating sheet and the insulating adhesive. Π | 5r 3: ;!.: ' I; |||; \ :, | ; i ^ [0007] ❹ The effect of the present invention is that the insulating sheets are closely sandwiched between the electrodes in series with each other. Between the plate and the fin, the difference in the mutual insulation of the insulating sheets has a wide tolerance range of thickness tolerance, thereby avoiding brittle cracking due to inaccurate flatness. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The detailed description and technical contents of the present invention are set forth in the accompanying drawings, and are in [0009] The present invention relates to a fin-type ceramic heater, please refer to the first to seventh figure 099102069 form number A0101 page 5 / total 23 hundred 0992004007-0 201127181, including a ceramic heating structure 100, A pair of electrode plates 200, a plurality of insulating sheets 300, an insulating adhesive 400, a pair of fins 500, and an insulating seal 600.

For example, aluminum, but not limited by this material, since the resistance value of the PTC ceramic heating sheet 110 is very large, the current can not pass completely, the electrode layer 120 can slightly lower the resistance value of the PTC ceramic heating sheet 110. The PTC ceramic heating sheet 110 can be allowed to pass current, so that the ceramic heating sheet 110 can exert the heating effect; and any two adjacent PTC ceramic heating sheets 110 are further filled with an insulating gel 130, The electrode layer 120 is respectively coated on the top surface and the bottom surface of the PTC ceramic heating sheet 110 to avoid arc short circuit. If a short circuit occurs, the PTC ceramic heating sheet 110 has no heating effect; The heating structure 100 further includes an insulating block 140 attached to the end of the PTC ceramic heating sheet 110 arranged at the outermost edge, or can be sandwiched between any two adjacent PTC ceramic heating sheets 110. However, it is not necessary to enhance the electrical insulation effect. The insulating block 140 is made of an insulating material, such as alumina, tantalum nitride, aluminum nitride, etc., but is not limited by these materials, and the CTI of the insulating block 140 is The (relative electric tracking index) is not less than 600, and the CTI is represented by a numerical value, which is a voltage value caused by electric leakage of the electrically insulating material in a standard test. [0011] The pair of electrode plates 200 are respectively attached to the ceramic heating structure 100. The top surface and the bottom surface, that is, the pair of electrode plates 200 sandwich the PTC ceramic heating sheets 110, which are made of a conductive material, such as aluminum, but are not limited to this material 099102069 Form No. A0101 Page 6 / A total of 23 pages 0992004007-0 201127181 system 'and the pair of electrode plates 2QQ are connected separately, the electricity is distributed - the ceramic "hot two: electricity due to the electrode layer 120 and the electrode plate 2. 〇 is the same conductive material 2 'example Μ , the electrode layer 12_ electricity does not shift or electron migration problems, and the pair of electrode plates 2

The difference of 110 from each other has a wider tolerance range of thickness tolerance, and it is less likely to cause brittleness due to inaccuracy of flatness. [0012] Ο the insulations Q are respectively attached to the side of the pair of electrode plates 200 in a string type and the width of the insulating sheet 3〇〇 is larger than the width of the electrode plate 2〇〇 (fourth figure) To avoid arcing, the end of the insulating sheet is gold. Straight, oblique φ, or bee ladder, then any two adjacent insulating sheets 3〇〇 may be mated, mitered, or plugged, etc. (such as the fifth to seventh figures) and are adjacent to A gap 310 is formed between the insulating sheets 300. The insulating sheet _ is made of an insulating material, such as oxidized Ming, Yihua Meng, Ni Niming, etc., but is not limited by these materials, and the number of the insulating sheets 300 is limited. The number of the PTC heating sheets 11{) can be the same, and the insulating sheets 300 are equal to the PTC ceramic heating sheets no.

The degree of deformation shock caused by thermal expansion and contraction can be reduced. [0014] The pair of fins 500 are respectively stacked on the outer surface of the insulating sheet 300 and the insulating adhesive 400, that is, the fins 500 and the electrode plate 200 sandwich the insulating sheets 300 and the insulating adhesive a glue 400, and the width of the insulating sheet 300 is larger than the width of the fin 500 (as shown in the fourth figure) to avoid the occurrence of an arc phenomenon and to prevent current from flowing from the electrode plate 200 to the chip 500. In this way, the degree of external insulation is enhanced, and the fin 500 can increase the heat dissipation capability, that is, enhance the heating effect of the heater as a whole, and the insulating sheets 300 are closely sandwiched between the electrode plates 200 because they are arranged in series with each other. Between the fins 500, the insulating sheets 300 have a wide tolerance of thickness tolerance, and are less likely to be brittle due to inaccuracy in flatness.
